ALEXANDER CHAMBLE Y, F PHILADELPHIA, PENNSYLVANIA.

VENTILATOR.

To all whom it'may concern Be it known that I, ALEXANDER CHAM- BLEY, acitizen of the United States, residing in Philadelphia, Pennsylvania,have invented certain Improvements in Ventilators,

of which the following is a specification.

One object of my invention is to pirovide a novel construction forventilating basements and other rooms, which, while allowing freepassage of air into the rooms, shall effectually prevent entrance ofwater, snow, &c., the invention contemplating an arrangement of partswhereby the quantity of air passing through the ventilator may be variedor regulated.

Another object of my invention is to provide a novel form of pavement ormonitor ventilator which shall be substantial, simple, and inexpensivein construction, with its parts so designed that when employed toventilate basement rooms, it shall not be likely to have its waterdrainage openings clogged but shall be capable of being easily inspectedand cleaned.

These objects and other advantageous ends I attain as hereinafter setforth, reference being had to the accompanying drawing in which,

Figure'l is a sectional perspective view illustrating my invention asconstructed to serve as a ventilator for basement rooms; and Fig. 2 is asectional perspective view illustrating my invention designed as a roofventilator.

In Fig. 1 of the above drawings, 1 represents a concrete or otherpavement having a more or less elongated opening (though other forms ofopenings may be employed) provided with a cover grating 2 which, in thepresent instance, is shown as supported. flush with the top or pavementsurface. Said grating is carried mainly by the vertical flanges of twoangle irons 3, the arrangement being such that while said flanges extendupwardly along the edges of the opening, the other flanges of saidangles extend horizontally into the concrete or other body of thepavement. Extending downwardly below the opening in the pavement is atrough shaped structure 4 preferably of sheet metal and made of such awidth that its side members are slightly farther apart than the width ofthe opening between the angle irons 3. These members are provided withoutwardly extended flanges 5 prefer- Specification of Letters Patent.

ably embedded in the concrete of the pavement under saidangle irons.

The trough 4 is connected at any suitable number of points to sewer ordrain pipes 6 and at a suitable distance above its bottom is providedwith a false bottom in the form of a grate'or perforated; plate 7carried in the present case on angle irons 8 fixed to the sides of saidtrough. In each of the vertical sides of the trough is a suitable numberof elongated openings or other suitably formed openings which may becompletely closed by dampers 9 preferably hinged to the lower edgesthereof in any desired manner. It will be understood that these openingsin the vertical sides of the trough structure 4: provide communicationwith the interior of a room or rooms from which the air is free to passthrough said opening into said trough and out through the openings ofthe grating 2. The flow of air through these openings may be controlledby adjusting the dampers 9, and obviously Water, snow, etc., enteringthe trough through the openings of the grating, is free to pass throughthe openings in the false bottom 7 into the lower part of said troughwithout possibility of entering the adjacent room through the openingsof the lower sides of said stucture. Any solid matter not passing outthrough the drain pipe 6 may be'removed from time totime, since accessmay be had to the bottom of the trough 4 by removing the grating 52 andthe false bottom 7.

In that form of my invention shown in Fig. 2, the construction employedis similar to that of Fig. 1 except that it is designed to provideventilation through a concrete trough structure or monitor 11 and regu-1 late the air passing through these by dampers 13 hinged to one edge ofeach opening, in the case shown,the bottom edge. As in the form of myinvention shown in Fig. 1, there is a free passage from the interior ofa room into the trough structure 4 and out through the openings orpassages 12 in the inverted trough 11, While any rain, etc., passinginto the ventilator through these passages necessarily passes into thebottom part of said trough 4 through the grating or false bottom 7 andthence to the drain pipe 6. Any large pieces of material which mightclog the drainage opening or openings lodge upon this grating and mayeasily be removed.

It is to be understood that by the term roof structure as employed inthe claims I refer not only to such a construction as that illustratedat 10 but also to any other form of roof, Whether it be applied to thecover of a building or to the cover structure of a room such for exampleas that illustrated at 1 in Fig. 1, Where, although said partconstitutes a pavement, it like- Wise serves as the cover or ceiling orroof of one or more basement rooms, it being obvious that so far as theinvention is considered, it is absolutely immaterial as to Whatconstruction or function is adopted for the parts 10 or 1.

I claim 1. The combination of a roof structure having an opening; atrough suspended in said opening and having an air passage in at leastone of its sides; a covering member for said trough, also having anopening; a perforated false bottom in the trough; and means forconducting Water from the trough.

2. The combination of a roof structure having an opening; a troughsuspended in said opening and having a passage in at least one of itssides; an adjustable damper mounted to control the flow of air throughsaid passage; a covering member for said trough, also having an airopening; means for conducting Water from the trough; and a perforatedfalse bottom in the trough for catching solid material.

3. The combination of a concrete roof structure having an opening; atrough having its free edges provided With flanges embedded in the roofstructure and suspending it from the same, there being an air passage inat least one of the sides of the trough; a covering member for theopening, also having flanges embedded in the roof structure; and meansfor conducting Water from the trough.

4. The combination of a roof structure having an opening; a troughhaving flanges embedded in the roof structure and suspended therebyunder the opening; a grating for the opening in the roof structure;flanged members embedded in the roof structure and supporting saidgrating; a perforated false bottom in the trough; means for conductingWater from the bottom of the trough; and adjustable dampers mounted inopenings in the sides of the trough.

In testimony whereof, I have signed my name to this specification, inthe presence of two subscribing Witnesses.

ALEXANDER CHAMBLEY.
